What happens if you don’t bleed your brake line?

  • If you have air in your brake lines, the air can compress when you step on the brake pedal. In that case the air compresses instead of the pressure being applied to the brake pads. If you have air in your brake lines the pedal will feel spongy. You can step on it sometimes and the pedal goes ƒᴀʀтher down before the car brakes.

    Hydraulic fluid (and all other fluids as far as I know) cannot compress like air (gasses) can.

    When you step on the brakes the brake fluid transfers the pressure in the master cylinder to the pistons in the brake drums or calipers, applying the brakes.

    Bleeding the brakes removes the air from the lines.

  • Your brakes will be very weak and possibly lead to an accident. It’s happened to me.

    You must bleed all the brake lines if you’ve done any maintenance to your brake system, for example, replacing a brake line, drum cylinder, etc.

    After you replace such parts, you will have air in the lines. Air compresses when you put pressure on it, which will cause loss of braking performance. All lines must be filled with brake fluid, and because liquid doesn’t compress, the brakes will be much stronger and reliable.

    To bleed the brake lines, you must have two people. Have one person pump the brakes with the car OFF to build pressure and hold pressure on the pedal when it won’t pump anymore, while the other loosens the bleeder valve on the brakes. When liquid comes out, or if the brake pedal hits the floor, tighten the bleeder valve. If the pedal hit the floor first, the pump the brakes again and repeat until fluid comes out. Be sure and keep brake fluid in the resivior, or you’ll be pumping air back in the lines. Do this for all four brakes, and keep an eye out for any leaks in the system.

  • Air in a hydraulic system is a recipe for failure, literally. It can cause your brakes to not enɡɑɡe or enɡɑɡe unevenly because of a lack of or improper levels of hydraulic pressure.

    Do yourself a favor and get a bottle of fresh brake fluid and an inexpensive bleeder kit at your local auto part store and get that air out.

  • Nothing, if you didn’t do anything to the hydraulic part of the brake system.

    But if you did replace something in the hydraulic part, then you will have little or no braking.

  • Change master cylinder and bleed the brakes and now after driving for about two to three hours my front brakes lock up can anybody help?????

  • You won’t build adequate hydraulic pressure in the brake line and you won’t have adequate stopping power and you will crash.

  • air trapped in the system acts as a compressable cusion resulting in spongy, low, or no braking. also as the air heats up under pressure, it vaporizes and water trapped in it, contaminating the entire braking system.

    and you could get into a serious crash.

    get them bled soon
